I finally got the HP45 Microcode running on a PIC Microchip.
Building a Keyboard with tactile Feedback and a nice LED- Display is easy, so I now have a calc working linke the HP-45 (even the stopwatch works). This calc will be called the IQ-45
I will continue to simulate more of the classics, next is the HP-55.
The Hardware costs are about 20 Euro.
Is anyone interested in the Firmware and Hardware? I don´t have a documentation yet, and if noone is interested, I do not have to compile one. So please answer this thread if you are interested.

OK, I will publish photos how to build the calc, (I don´t want to draw the schematics), a short hardware-description and the PC simulation as soon as possible. I am still improving the PIC-Software, but I will release the files. Greetings.
